Хотелось автоматизировать Импорт в реестр ключа MTU в ветке HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{.........}, понятное дело что запуском *.reg файла не обойдешся.
ВОТ код, правда сыроват, может кто поможет, своим профессиональным советом. Проверено на компьютерах с одной сетевой картой и одним IP адресом
